Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WA R N I N G
Using Different Tire Types:
Driving your vehicle with different types of
tires is dangerous. It could cause poor
handling and poor braking; leading to loss
of control.
Except for the limited use of the temporary
spare tire, use only the same type tires
(radial, bias-belted, bias-type) on all four
wheels.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for the vehicle (page 9-9) is
dangerous. It could seriously affect ride,
handling, ground clearance, tire clearance,
and speedometer calibration. This could
cause you to have an accident. Use only
tires that are the correct size specified for
the vehicle.
▼ Tire Inflation Pressure
WA R N I N G
Always inflate the tires to the correct
pressure:
Overinflation or underinflation of tires is
dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-9.
Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly when the
tires are cold. Maintain recommended
pressures for the best
ride, handling, and
minimum tire wear.
Refer to the specification charts (page
9-9).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel
economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,
uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequen tly needs inflating,
have it inspected.

CAUTION
When inserting the air compressor plug
into or removing it from the accessory
socket, make sure that the air
compressor switch is off. When turning
the air compressor on/off, use the air
compressor switch.
12. The sealant is injected into the tire
when the air compressor is switched
on. After the sealant is injected
completely, wait until the tire inflation
pressure increases to the specified tire
inflation pressure.
NOTE
The inflation pressure may increase to
about 300 kPa (3.1 kgf/cm
2, 3 bar, 43.5
psi) temporarily to inject the sealant
through the valve. Normally, the
inflation pressure decreases gradually
and it reaches the actual inflation
pressure after about 30 seconds.
WARNING
Never use the air compressor above 300
kPa (3.1 kgf/ c m
2, 3 bar, 43.5 psi):
Using the air compressor at an inflation
pressure above 300 kPa (3.1 kgf/cm
2, 3
bar, 43.5 psi) continuously is
dangerous. If the air compressor
overheats, hot air will be exhausted and
you could get burned.
NOTE
Check the tire inflation pressure
label driver's door frame for the
correct tire inflation pressure.
Do not operate the air compressor
for a continuous 10 minutes or
longer because using it for long
periods could cause a malfunction.
